Changelog

2026-05-01 - 6.1.0 - feat(smartenv)

add Bun and Deno OS detection support and update test runtime compatibility

extends async OS detection helpers to work in Bun and Deno by loading the appropriate os module for each runtime
improves runtime-specific typings and safe global access for Deno, Bun, and importScripts usage
updates tests to export tap.start(), rename the browser test target to chromium, and clean up console output for newer test tooling
refreshes build and test tooling configuration and package metadata for the current release workflow

Add Deno and Bun runtime detection, introduce getSafeModuleFor API, update docs and tests, and make isNode semantics Node-only (breaking change)

Implement runtime detection for Deno and Bun; runtimeEnv now returns one of 'node' | 'deno' | 'bun' | 'browser'.
Change isNode to be true only for Node.js; add isDeno and isBun accessors. This is a breaking change in behavior for code that relied on isNode including Deno/Bun.
Add getSafeModuleFor(target, moduleNameOrUrl, getFunction?) API to load modules conditionally for single, multiple or 'server' runtimes. Existing helpers getSafeNodeModule and getSafeWebModule updated to work with wider runtimes.
Add runtime-specific version getters (nodeVersion, denoVersion, bunVersion) and update printEnv output accordingly.
Expand and add tests for Node, Deno, Bun and Browser environments (tests/* files).
Update documentation (readme.md and readme.hints.md) to describe detection order, new API and migration notes from 4.x to 5.x/6.x.
Bump devDependencies (tsbuild, tsrun, tstest) and include an updated deno.lock.

Updated readme.md with comprehensive documentation including API reference, core features, and usage examples
Added readme.hints.md with architecture and implementation details for future reference
Improved documentation structure and clarity
